Summary

Microplastics and nanoplastics have been detected in human placentas, meconium, and infant faeces, meaning babies can be exposed before and immediately after birth. This review examines what these early-life exposures might mean for infant health and development, and discusses broader policy responses to reduce plastic overproduction as the most direct route to protecting future generations.

Body Systems

Microplastics and nanoplastics (MP/NPs) have been found everywhere they have been searched. On the top of Everest, in the Mariana Trench, on the clouds e recently, microplastics have been discovered in the human placenta, meconium and babies’ feces. In this review we explain what the consequences of the presence of these pollutants in fetuses and newborns are, with particular attention to human breastfeeding. Finally, we outline the possible political and social solutions to the problem of plastic overproduction that characterizes the modern world.

Impacts of micro- and nanoplastics on early-life health: a roadmap towards risk assessment

Researchers proposed a detailed risk assessment roadmap specifically for how micro- and nanoplastic exposure during pregnancy and early childhood could harm fetal and infant development, noting that these tiny particles have already been detected in human placentas. The framework identifies critical gaps in dosing data, detection methods, and placental transfer research needed before reliable safety conclusions can be drawn.

Detection of various microplastics in placentas, meconium, infant feces, breastmilk and infant formula: A pilot prospective study

In a pilot study of 18 mother-infant pairs, researchers detected microplastics in placentas, meconium (first stool), infant feces, breast milk, and infant formula. The finding of microplastics in breast milk and formula means that infants are exposed to microplastics from their earliest feedings, both natural and artificial. This study reveals that microplastic exposure begins before birth and continues through infancy, a critical period of development.

Hidden Threats in Infant Diets and Environment ‒ Risks of Microplastics and Nanoplastics in Food

This review examines how infants aged 0-12 months are exposed to microplastics and nanoplastics through inhalation and ingestion, with plastic packaging and food preparation being major dietary sources. Researchers found that these particles can cross biological barriers, leading to systemic exposure that may affect infant development. The study calls for more comprehensive research to understand the long-term health implications of plastic particle contamination in infant diets.

From Cradle to Grave: Microplastics—A Dangerous Legacy for Future Generations

This review examines how microplastics affect human health from before birth through death, covering fetal exposure through the placenta, childhood ingestion, lifelong accumulation in tissues, and eventual release back into the environment. Evidence shows that microplastic exposure begins in the womb and continues throughout life, with particles building up in organs over time. The authors argue that microplastics represent a generational health threat that requires urgent attention.

Health Implications of Microplastic Exposure in Pregnancy and Early Childhood: A Systematic Review

This systematic review summarizes existing research on how microplastic exposure during pregnancy and early childhood may affect health. The evidence shows that microplastics can reach the placenta and may cause oxidative stress and inflammation, raising concerns about potential effects on fetal development and infant health during these vulnerable life stages.
